Research And Design Of Content-Oriented Edge Network Blockchain Smart Contract

With the continuous development of Internet technology and the rise of the mobile Internet era,more and more people are spending their free time on the Internet.The emergence of streaming media has enabled more people to enjoy better video services.Streaming video is directly directed to the majority of user groups,and it has higher requirements for the viewer's network environment,because users are watching video while receiving video data.If the user experience is poor due to network quality issues,it will reduce user stickiness..Generally speaking,the same video resource will be downloaded or watched online by multiple users.If these edge users can be gathered to provide services for other users in need,the resources of the edge nodes will be fully utilized to improve the performance of video transmission.Significant lifting effect.In real life,how to make better use of limited resources to improve Qo S(Quality of Service,service quality)has become a problem that streaming media service providers generally pay attention to.This article analyzes the advantages and disadvantages of the current video-on-demand system,combined with blockchain smart contract technology,design a video on-demand system based on blockchain smart contract,the main content is as follows:(1)By analyzing the shortcomings of the virtual currency-based incentive mechanism,combined with the decentralized nature of the blockchain,a blockchain-based incentive mechanism is proposed.(2)By comparing the traditional CDN and P2 P service modes,find the applicable scenarios of the two modes,and propose a mixed streaming media distribution model based on the advantages of the two.(3)Combine the hybrid streaming media distribution model with the blockchain smart contract.Taking the blockchain as the core,taking smart contracts as the key to logical interaction and fully considering the security of smart contracts,a video-on-demand system with a competitive mechanism is designed.(4)Build a blockchain smart contract development environment,design a smart contract model,complete the overall design of the system through software development,and test its functions.The design concept of this article is mainly to reduce the waiting time of the experiencer as much as possible under the premise of providing users with more high-quality and stable video services.In addition,the traffic consumed by the main transmission network within the system is also minimized,and the cost of watching videos is reduced as much as possible.At the same time,based on the characteristics of CDN and P2 P,a reasonable transmission scheme is designed to provide user nodes with efficient and orderly services.In addition,the proposal of incentive mechanism,monitoring mechanism and punishment mechanism is conducive to improving the system service environment,controlling P2 P nodes reasonably and effectively,and the system performance and continuous operation ability are greatly improved.
